  • Apples Catalogue 2019
    ADAMS PEARMAIN Herefordshire, England 1862 Oct 15 Nov Mar 14 Adams Pearmain is a an old-fashioned late dessert apple, one of the most popular varieties in Victorian England. It has an attractive 'pearmain' shape. This is a fairly dry apple - which is perhaps not regarded as a desirable attribute today. In spite of this it is actually a very enjoyable apple, with a rich aromatic flavour which in apple terms is usually described as Although it had 'shelf appeal' for the Victorian housewife, its autumnal colouring is probably too subdued to compete with the bright young things of the modern supermarket shelves. Perhaps this is part of its appeal; it recalls a bygone era where subtlety of flavour was appreciated - a lovely apple to savour in front of an open fire on a cold winter's day. Tree hardy. Does will in all soils, even clay. AERLIE RED FLESH (Hidden Rose, Mountain Rose) California 1930’s 19 20 20 Cook Oct 20 15 An amazing red fleshed apple, discovered in Aerlie, Oregon, which may be the best of all red fleshed varieties and indeed would be an outstandingly delicious apple no matter what color the flesh is. A choice seedling, Aerlie Red Flesh has a beautiful yellow skin with pale whitish dots, but it is inside that it excels. Deep rose red flesh, juicy, crisp, hard, sugary and richly flavored, ripening late (October) and keeping throughout the winter. The late Conrad Gemmer, an astute observer of apples with 500 varieties in his collection, rated Hidden Rose an outstanding variety of top quality.

  • Assessment of Apple Cultivars for Organic Fruit Growing
    Agronomy Research 7(Special issue I), 363–368, 2009 Assessment of apple cultivars for organic fruit cultivation J. Lanauskas, A.Valiuškaitė, N. Kviklienė, A. Sasnauskas and N. Uselis Lithuania, Lithuanian Institute of Horticulture, Orchard management department, Kauno 30, LT-54333 Babtai, Kaunas distr., Lithuania; e-mail [email protected] Abstract. In 2005–2008 apple tree cultivars and selections were tested at the Lithuanian Institute of Horticulture in an organic apple tree orchard. Apple trees on rootstock B.396 were spaced at distances of 4 x 2 m; the orchard floor was a cultivated soil. The bioinsecticide Bioshower against aphids was applied once a year, fungicides were not used. Apple trees of cultivars. ‘Pilot’ and ‘Pinova’ were significantly affected by apple scab (Venturia inaequalis Cke. Wint), and ‘Lodel’ – by apple powdery mildew (Podosphaera leucotricha (Ellis et Everh.) Salm). Apple trees of the cultivar. ‘Aldas’ and selection 18501 were the most vigorous. In 2007– 2008 the greatest average yield was from the cultivars ‘Florina’, ‘Rosana’, selections 20,490 and 22,1709.1–14.7 t ha-1. These same cultivars and selections were the most yield efficient. The greatest average fruit weight was from cultivar. ‘Witos’ (272 g), the smallest from the cultivars ‘Pilot’, ‘Pinova’, ‘Goldrush’ and ‘Lodel’ (111–137 g). The highest taste score was from ‘Goldstar’, ‘Rubinola’, ‘Topaz’, ‘Rajka’ and ‘Lodel’ apples. Key words: apple scab, yield, fruit weight, taste INTRODUCTION Technological progress in agriculture and related branches of industry has resulted in an increase in agricultural production. Highlydeveloped countries produce more food than they consume themselves. People concerned about their health have begun to seek more healthy products.

  • Organic Apple Production in Sweden: Cultivation and Cultivars
    Organic Apple Production in Sweden: Cultivation and Cultivars Å.H. Jönsson Faculty of Landscape Planning, Horticulture and Agricultural Science Department of Crop Science Balsgård Doctoral thesis Swedish University of Agricultural Sciences Alnarp 2007 Acta Universitatis Agriculturae Sueciae 2007:14 ISSN 1652-6880 ISBN 91-576-7313-8 © 2007 Åsa Jönsson, Balsgård Tryck: SLU Service/Repro, Alnarp 2007 Abstract Jönsson, Å. 2007. Organic apple production in Sweden: cultivation and cultivars. Doctor’s dissertation. ISSN 1652-6880, ISBN 978-91-576-7313-8 Consumer interest in organically grown fruit appears to have increased considerably in recent years but the organic apple growing in Sweden cannot match the demand. One objective of this thesis was to study conversion of an orchard with ‘Aroma’ and ‘Karin Schneider’ from IFP to organic production. The accumulated yield for both cultivars was slightly lower in the organic sections compared to the IFP-grown sections, due mainly to a lower number of fruits while fruit size remained the same. In organic sections, 10% of the fruit was damaged by scab but less than 1% in the IFP sections. Aphids and NTG (noctuids, tortricids and geometrids) inflicted the highest amount of insect damage and this damage was higher in the organic sections. No major treatment effects were found in fruit covering colour, ground colour, firmness, sugar content or malic acid content. Two observation trials with apple scab-resistant cultivars and one with cultivars suitable for organic production of fruit for industrial use were also carried out. In Trial I, the most productive cultivars were ‘Bio Golden’ and ‘Topaz’, and in Trial II ‘Vanda’ and ‘Scarlet O’Hara’.

  • Effects of Climatic Conditions on Fruit Quality of Apple Cultivars Assessed by Public Sensory Evaluations in the Czech and Slovak Republics 1999-2004

These leaders were mainly followed by ‘Topaz’, ‘Angold’ and a group consisting of ‘Jonagold’ and several of its mutants. In contrast, ‘Golden Delicious’, ‘Gloster’ and ‘Melrose’ performed well only at the warm and moderately warm locations. ‘Braeburn’ performed well only at the warm location. On the other hand, ‘Fuji’ and ‘Pink Lady’ performed only averagely at the warm location, and were barely acceptable in very warm years. Of the new cultivars, ‘Meteor’ was the best performer at the moderately warm location, and ‘Stella’ was the best performer at the cold location.

The census provides an important overview of apple production, and comparisons are made to previous censuses (2007, 2002 and 1997) where possible. The census surveyed all commercial orchards, defined as follows: - a production area of at least 0.2 hectares of apples, including cider apples - the fruit from the orchard is sold every year - the orchard is sprayed against pests/diseases every year, or maintained to organic standards Within the 45 growers, there are two organic growers. Production areas are based on areas planted up to March 2012.

  • A Manual Key for the Identification of Apples Based on the Descriptions in Bultitude (1983)
    A MANUAL KEY FOR THE IDENTIFICATION OF APPLES BASED ON THE DESCRIPTIONS IN BULTITUDE (1983) Simon Clark of Northern Fruit Group and National Orchard Forum, with assistance from Quentin Cleal (NOF). This key is not definitive and is intended to enable the user to “home in” rapidly on likely varieties which should then be confirmed in one or more of the manuals that contain detailed descriptions e.g. Bunyard, Bultitude , Hogg or Sanders . The varieties in this key comprise Bultitude’s list together with some widely grown cultivars developed since Bultitude produced his book. The page numbers of Bultitude’s descriptions are included. The National Fruit Collection at Brogdale are preparing a list of “recent” varieties not included in Bultitude(1983) but which are likely to be encountered. This list should be available by late August. As soon as I receive it I will let you have copy. I will tabulate the characters of the varieties so that you can easily “slot them in to” the key.

There was a significant effect of fruit position in the canopy on heat accumulation in fruit surface. Fruits born in southern part of the canopy were more heated than those from other tree parts. It was found that a blush contributed to an increase of fruit temperature, especially those from southern parts of the canopy.
